Patented May 9, 1933 UNITED STATES V BIAGIO GERMANA, OF CLEVELAND, OHIOCORNIGE MOLD-CUTTER AND FINISHER Application filed March 16, 1931.

My invention is an improvement in plastering tools and relates moreparticularly to such devices for use in cutting, molding or formingcornices from plastic materials.

One of the objects of my invention is a tool for forming cornices ofplastic materials and which is extremely simple of construction and easyto operate.

It is also an object of my invention to provide a cornice tool which maybe converted for use in places where either inside or out side cornersare encountered.

Another object of the invention is to provide a tool for formingcornices which requires only one person to operate the same.

A still further object of the invention is the provision of a cornicetool which maybe used with interchangeable blades or cornice formingmembers to permit the forming of cornices in different designs.

Other objects and advantages of my invention will become more apparentas the following description of an embodiment thereof progresses,reference being made to the accompanying drawing, in which likereference characters are employed to designate like parts throughout thesame.

In the drawing Figure 1 is a top plan view of an embodiment ,of myinvention showing the same adjusted for forming cornices along wallsintersecting to form an inside corner.

Figure 2 is a side elevation looking in the direction of the arrows 2-2of Figure 1.

Figure 3 is a top plan view similar to Figure 1 except that the bladesare adjusted to a substantially relative parallel position.

Figure 4 is a fragmentary enlarged elevation looking in the direction ofthe arrows 4t of Figure 1.

Figure 5 is a front elevation of a slightly modified form of the tool.

Figure 6 is a top plan view of the tool showing the blades adjusted forforming cornices along walls intersecting to form an outside corner.

Figure 7 is a section taken on line 77 of Figure 5.

In carrying out my invention as shown by the embodiment illustrated inthe drawing,

Serial No. 522,931.'

I provide base 1 which is substantially triangular in form and which isintegrally or separably connected to a handle 2. The handle 2 may beconveniently shaped for com fort in the use of the tool, there being anupwardly extending portion 3 having faces 4 and 5 arranged at rightangles for purposes which will be more fully described hereina ter. I

Pivoted to the base 1 are a pair'of bladecarrying plates of supports 6.-These plates may be formed of wood or cast in metal, such as aluminum orthe like. Theplates 6 are preferably pivoted to the base at 7 by meansof pins 8 and may be swung about vertical axes to the positionsindicated in Figuresl, 3 and 6. I have provided stops 9 securedto thebase 1 whereby the movement of the plates 6 about their pivots may belimited in either direction. Ihese stops 9 also serve to properly alignthe plates in either of their positions so that the cornice formingblades may be properly positioned for use.

It will be noted that the faces 4 and 5 of the post 3 closely fit theadjacent faces of the plates 6 when either one or both the plates are inthe position shown in Figure 1. In this manner, greater rigidity isimparted shown in Figure 1. In this manner, greater rigidity is impartedto the tool and substan-- tially perfect alignment of'the blades 10 isobtained.

Each of the plates 6 is adapted to receive a cornice forming blade 10.These blades may be removed and interchanged with other blades havingother desirably arranged or designed cornice cutting or molding edges.If desired, the plates may be removed from the base, and otherplatesinterchangedtherewith with cornice plates attached. I haveprovided means for permitting the use of supports and blades of largerarea than those indicated in solidlines in the drawing. Such means mayinclude adjustable shoes 12 operating in the base 1 and vcapable ofbeing locked in any desired adjustment by means of the set screws 13.

In this manner the base 1 may be adjusted toward or away from the wallon whichthe.

ends 15 for insertion in the fasteners 16 carried by the upright 3.\Vhen the connecting rods 14 are not in use they may be supported inclips 17 carried by the respective plates or supports 6.

When it is desired to lock either or both the plates 6 in the positionshown in Figure 1, they may be so locked by means of pins or screws 18operating transversely ofthe 7 post or upright 3.

In use, the embodiment of my invention shown in the accompanying drawingmay be operated as follows.

First assuming it is desired to cut, mold or form a cornice along twowalls intersecting to form an inside corner, such as is illustrated inFigure 3, the plates 6 may be adjusted and locked in either of thepositions illustrated in Figures 1 or 3. The forward wall engaging faceof the base 1 is placed against the wall as indicated in Figure 3. Theoperator grasps the handle 2 and with one stroke toward the insidecorner of the intersecting walls may form the cornicefrom a quantity ofplastic material previously-applied to the wall, the blades 10' cuttingand forming the plastic material as the tool is moved to the left towardthe corner. With the plates Gin the posit-ion shown in Figure 1 it isobvious that a cornice may be formed along one of the intersecting wallsby a single movement of the tool along the wall in a direction towardthe corner.

The tool may then be placed against the adjacent intersecting wall andin one movement toward the corner will form a similar cornice on thiswall. Since the blades 10. are arranged at an angle of 45 with respectto the wall with which the tool is in engagement the completion of theforming stroke of the tool along either wall in the corner formed by thewalls will result in perfectly matched cornice where these cornicesintersect. hen the blades are arranged in substantial parallel relationas in Figure 3 the blade 6 to the left will act as a primary cutting orforming blade while the other blade will serve as a finishing orsmoothing blade. y

When it is desired to form or mold cornices with the tool along wallswhich intersect to form a so-called outside corner, the blades may bearranged as illustrated in Figure 6.

To accomplish thisnthe fasteners 18 are removed and the plates 6 areswung about their piwots to the position shown. The connecting rods 14are released from the clips 17 and their hooked ends are inserted in thefastener 16 carried by the upright 3. In this manner the plates arerigidly supported in the desired positions for forming a cornice on anoutside corner. The operation of the tool in this connection is similarto that explained above.

In either form of my invention when it is desired to substitute largerblades or plates forthose shown in the drawing this may be done by firstremoving the blades or plates shown if the wall engaging ends of thesubstituted blades or plates extend beyond the wall engaging face of thebase 1, the shoes 12 may be extended as shown in dotted lines inFigure 1. The shoes 12 may be locked in such extended positions by meansof the,

set screws 13.

In Figure 5 I have substituted a stop plate 18 for the stops 9 shown inthe other views, the same serving to limit the movement of the plates inone direction.

I have also shown means for removably maintaining the plates in eitheradjusted position. Such means may. be located near the stop plate 18aand near the converging outer edges of the base 1, and include a cuplike 5' member 20 seated in the base. A ball or plunger 19 having anupper rounded surface extending above the top of the base 1 operatesagainst the compression of the spring 21 in the cup. The under sides of.

the plates 6 are provided with'a socket for engaging the balls orplungers when the plates are in either of their extreme limits ofmovement. In Figure .7 this means is illustrated in slightly enlargeddetail.

Various changes in the details of construction and arrangement of partsmay be made without departing from the spirit of my invention or thescope of the appended claim.

I claim: I

A cornice tool including a base, an operating handle and a plurality ofblades carried by the base, said blades being pivotally adjustableonjthe base, and shoes carried 1 by the base for spacing thebase from awall on which the cornice is to be formed.

In testimony whereof, I hereunto afliX my signature.

BIAGIO GERMANA.
